This invention relates to an improvement in dust collectors for 'usewith coal burning furnaces, etc, and comprises a device of this class adapted to be fitted upon and cover the top of an ash receptacle. j

Thedevice is adapted to be used in connection with any receptacle or; device to receive ashes when removedfrom'a furnacefand to permit the handling of said ashes without the usual accompaniment of dus't-inthe furnace room." I r It is well knownthat other devices ofthis general character vhave'been produced but it is believed that they are more or less inefiicient. For example,,'certain ofthes'e devices are no more than a cover to an ash receptacle and are directly. connected with the. chimney when the ashes are emptied into the covered receptacle, is properly carried off, the structure is such that considerable dust arises in conveying the ashes from the furnace to and placing within the ash. receptacle. Other devices ofathis .chara cter'areadapted to be 7 chute of any kind bywhich theashes maybe easily placed within the ash receptacle. In applicants experience ith'as been found that in order to properly; handle, ashes, a device, must be provided which has anaccessible opening or chute andwhichmay be closedto prevent any of the ash dust from passingout of the receptacle intothe furnace room.

This invention has thereforesfor its principal object the provision of a device of this character connected with the smoke pipe or chimney of a heating furnace and which is adapted tobe applied to the top of an ash receptacle for removing the dust therefrom by the draft'which obtainsin the smoke pipe.

, Another object ofthis'inve'ntion is to provide a device of this character which is fitted with a chute by which ashes may be easily placed within. the receptacle and closure 'means by'which tocorifine the dust; further object ofthis invention lies in an ash receptacle; orfluefi While the Iash;-dust,"which rises a V 'ure 2; z stances, are not provided; with doors or a 1929. 7 Serial no 377,741)

the provision'of adevice of this character which, being adjustable, may be fitted upcn ash receptacles varying in size. I Another'and further object of thisinVenP tion is the provisionof' a device of this class having an adjustable wall which is adapted to receive an ash'receptacle cover of what- ,eversizereceptacle said device is adjusted foruseupon. I 1

Other and further'objects of thisginvention will appear from a consideration of the following specification when taken in conjunction with the accompanying drawings which form a part thereof, and in which Fig. 1 is a side elevation of one'modi'fication of this invention shown mounted upon Fig. 2 is a horizontal sectional view of the structure shown in'Figure' 1, taken substantially on line 2-2 of that figure; r I 7 Fig.1 3 is a fragmentarysectional view showing the' door securing means, being. taken on the line"3'3 of Figurel; Fig. 4 is a front elevation of the device; @Fig- 5 is a'vertical sectional view of the 1 device showingthe door inopen position, being taken substantially on line 5- 5 of Fig Fig. 6-is a plan view ofone of the hood' elements mounted on .the frontof the device Fig. 7 is a side elevation of the door.

7 Referring to the dra'wingand particularly to'Figure 1 thereof, this invention is shown for'use upon an ash receptacle generallyfindi cated by the reference numeral 10. The receptacle 10, is shown formedl with a rolled edge orloead 1'1.' The dust collector '12 is formed with an opening 14in the vertical wall 15 thereof. 9 Secured in the opening 14' is a collar 17 upon which is mounted'a pipe 18. This pipe communicates with a suitable fine or chimney generally. indicated at 19.

The receptacle 10 is provided with a cover 21 1 having a handle22. The cover 21 terminates along its circumferential edgeina-verticalfiange'2t. When the dust collector 12 is placed upon thereceptacle 10, thecover 2 1is placed upon the collector and forms the top wall of the combined recep'tacle and 'dust collector. Y

, Thedust collector 12 is formed from two "walls 15jand 25. llhe wall 15,-cnstituting: j approximately two-thirds ofthe device, termina'tes in a rolledor flanged edge 27 adjacent oneside ofthe'dooropening.;. The other 7 'vertical edge of the'wall 15 is joined-to the wall 25'by means of bolts28 which are passedthrough suitable openings in said walls. A number of openings are provided in hori;

f zontal alignment in the wall25 in order that the diameter of the devicemay' be enlarged l or reduced according to the size ash receptacleupon which the dustfcollector is to be fitted. When in use with a small receptacle, the device 12. will;be of a reduced sizesubstantially as shown in'Figure'2 of the draws ing, whereas, when 'usedupon a large ash receptacle, thev ad acent ends of the Walls 15 and 25 will overlap each other only a sufiicient distance. topermit centering of the openings I and the insertionlof bjolts 28. The end of the wall 25, remote from the wallllifte'rminates in. an inwardlyturned flange 31. I

33 (see Fig. 6). The plate 33 is formed with a Vertical wall 34"{which terminates in. end,

flanges 35; Formed integral withthe wall 34 and extending horizontally from the upper edge thereof is .a hood 37. The 'hood'37,

s Well as the flanges 35,-are shapedto con 35 form to the; general circumferential curve of the walls and 25. TheIplate 33, along the :flanges 35 is'secured atone end to the wall I and at the other-end to the wall 15, in any suitahle'manner as by welding or riveting.- The lower plate 38 is supported by means of flanges upon the ends of walls 15' and2'5.

V Inthis instance it is essential to provide securing means for the rod39 and therefore r jstraps'lO' are secured to the vertical wall 3% ofthe plate 33 by means ofrivets 41. The

other ends of thestr'aps are joined to walls 15" and 25- by means of r'ivetsF L3. The straps 4O the ends 120f the rodareinserted. A door 47, having a curled edgell8,is fitted upon the horizontal portion of the rod 39. Thedoor is 'formed with a straight face to which is V ,secured a suitable handle 49; 'Projecting at right angles tothe'face of the door 47 are wings, 51 which, when the door is opened v (see Fig. 5) guide ashes' into the dust collector and ash receptacle,

' Itwill benoted that a series of'proj ections' "153 are formedin the'wall 15in any suitable manner, preferably, however, as shown in the -drzmning. The lowe'redge 5401 each projec- "tion "lies substantially in horizontal align ment with the hood 37 of the plate When the dust collector 12 is placed upon the receptacle 10, the projections 53 and plate 325 act to support saidcollector in the position substantially as shown in Figure 1 of the drawing. Since the faceof the dust'collector is flat and does not conform to the generally 7 cylindrical contour of the device, there would beaspace throughwhich ash dust couldrise from the receptacle were it not for the .provi-Y sion of the plate 33*. Furthermore, this 'is' true ofthe upper portion of the dust collector, for example, the cover 21 of the receptacle 10 would not completely close the top a of the dust collector "without the hood 37, which extends horizontally tocomplete the cylindrical shape of thedevice. r

It is to be'understoodthat'by removing the bolts 28, the size of-thedustcollectormay 'be increased or decreased as is necessary to fit'it upon a given ash-receptacle. Alter ing the size of the device permits the manu v means of which ashes are. placed within the dust collector, the wings 51 providlng -su1t' able'wa-lls to prevent spilling the lashes.

tion. In other words no latch or fastening of any hind is necessary torprevent undesired openlng of'the'door, since the weight of the wings 51 is suliicient to accomplish this-rpur :pose;

; While onlyon'e modification of this inven -f tion has been shown and descrihechapplicant doesnotintend to'be limited thereto 'since'it' is obvious that other modifications or'adaptations maybe made'without departing from tection'by Letters Patent is i formed from two relatively adjustable walls,

'85 which will fit all ash receptacles without reg rd-forsize. I

WVhen the door 47 isclosed, however, the f wings 51 constitute a 'weightfby 'meansof which said dooriis retained in its closed posie 1 7 'thejspirit and scope ofthis'inventionas set 1 .fort'h inthehereunto'annexedclaims. f
